ELASTIC FABRIC.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed September 30, 1911. Serial No. 652,163.

To all whom it may concern:

Be it known that I, WALDEMAR Kors, a citizen of the United States, residing at the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Elastic Fabrics, of which the following is a specification.

My invention relates to an elastic fabric or webbing of parallel sided form, and the method of weaving the same with the object of providing an elastic fabric suitable for use under tension and yielding conformably to irregularities of surface, wherever such forms of elastic fabric are useful in the arts and manufactures.

My invention consists of a strip of flat, elastic fabric or webbing composed of alternate and offset or staggered elastic and inelastic sections in the integral strip. These parts may be of any length and width.

In the fabric of my invention the warp threads and elastic strands run parallel and in length with the selvage and the weft threads, as usual, at right angles thereto. In the inelastic parts as woven I employ additional weft threads or filling, to bind and securely hold the elastic strands and warp threads of usual material securely together, all of which is hereinafter more particularly set forth.

In the drawing Figures 1 and 3 illustrate forms of my invention by diagrammatic plan views, or in other words, by plan views made as if the fabric or webbing was shown as under tension, and Fig. 2 is a section on the dotted line at w of Fig. l, in larger size.

Similar letters and numerals of reference indicate similar parts.

05 represents the elastic sections, 22 the 'inelastic sections, 2 and 3 the edges or selvage 4 the elastic strands, 5 the warp threads and 6 the weft threads.

As illustrated, there is an imaginary line of demarcation in Fig. 1 at the center of the fabric or webbing on one side of which is an inelastic section and an elastic section on the opposite side, and in the length of the fabric or webbing these parts alternate and are reversed, and when considered as a whole the elastic sections at the opposite edges of the strip are ofl'set or staggered with reference to one another. The in elastic sections are also the same way; consequently, as hereinbefore stated on each imaginary half of the fabric or strip lengthwise the elastic and inelastic sections alternate.

The warp threads of suitable material and the elastic warps, as usual, run parallel and the elastic warps spaced between series of warps of usual material and the weft threads run across the fabric or strip from selvage to selvage. The inelastic sections are formed by additional weft threads placed between the weft threads that run across the fabric or webbing and these additional weft threads which in length are only the width of the inelastic sect-ions make it possible to pack the fabric or webbing so tightly in the sections F) as to cause them to become inelastic.

In the form of my invention shown in Fig. 3, the inelastic sections 6 are narrower than those in Fig. 1, thereby increasing the Width of the opposing elastic sections a-. The respective ends of the marginal inelastic sections overlap and are connected transversely of the strip of webbing by inelastic parts so that in the webbing there are transverse inelastic parts 5 of the width of the webbing adapted for severing the webbing along the dotted lines 00 :0 into gore sections.

This fabric or webbing is useful in the arts or manufactures in any place where irregularities of surface are to be conformed to by a fabric or webbing, and in doing this the fabric stretches alternately in the op positely placed elastic portions to conform to irregular surfaces.

I claim as my invention:

1. A flat Stripelastic fabric or Webbing woven in one plece and having alternate elastic and inelastic sections arranged along opposite edges or parts of fabric or webbing, with the sections on one side staggered in relation to the sections on the other side.

2. A flat strip elastic fabric or webbing having alternate sections along the opposite edges formed inelastic by the addition to the usual weft threads of intermediate or filling weft threads which pack the said sections and cause them to be inelastic, and the sections along one side placed alternate or staggered with reference to the sections along the opposite side.

3. An elastic fabric or Webbing composed adapted to be cut through to form gore secof alternate elastic and inelastic sections artions. Y V V ranged along opposite edges or parts of. Signed by me this 22nd day of Septemfabric or Webbing, with the sections on one ber 1911.

5 side staggered in relation to the sections on WALDEMAR KOPS.

the other side, and the respective ends of the Witnesses: inelastic or sewing sections connected across ARTHUR vH. SERRELL, the Webbing by transverse inelastic parts 7 V MARY E. LELAND.
